Adaptive controller using unmeasured operating parameter

A system, comprising:

• a real-time engine model module configured to:
• receive at least one feedback signal indicative of a measured operating parameter of an engine;
• determine an engine parameter estimate signal based on the at least one feedback signal indicative of the measured operating parameter of the engine, wherein the engine parameter estimate signal represents an unmeasured operating parameter of the engine, different from the measured operating parameter of the engine;
• and
• an adaptive control module configured to:
• receive a power request signal;
• receive, from the real-time engine model module, the engine parameter estimate signal;
• determine a demand signal based on the power request signal and the engine parameter estimate signal, wherein the adaptive control module is configured to determine the demand signal based on the power request signal and the engine parameter estimate signal using a set of control laws;
• and
• output the demand signal to control at least one component of the engine.

A computer-readable storage medium storing instructions that, when executed, cause a processor to:

• receive, by a real-time engine model module, at least one feedback signal indicative of a measured operating parameter of an engine;
• determine, by the real-time engine model module, an engine parameter estimate signal based on the at least one feedback signal indicative of a measured operating parameter of an engine, wherein the engine parameter estimate signal represents an unmeasured operating parameter of the engine, different from the measured operating parameter of the engine;
• receive, by an adaptive control module, a power request signal;
• receive, by the adaptive control module, from the real-time engine model module, the engine parameter estimate signal;
• determine, by the adaptive control module, using a set of control laws, a demand signal based on the power request signal and the engine parameter estimate signal;
• and
• output, by the adaptive control module, the demand signal to control at least one component of the engine.
